NXP Semiconductors LPC1830FET256,551

Overview

LPC1830FET256,551 from NXP Semiconductors is a 32-bit ARM Cortex-M3 flashless microcontroller operating at up to 180 MHz, featuring 200 kB on-chip SRAM, dual high-speed USB 2.0 interfaces (one with integrated HS PHY, one with ULPI), and an Ethernet MAC with IEEE 1588 time stamping - deployed in industrial gateways requiring deterministic real-time connectivity and peripheral consolidation.

For engineers reviewing the LPC1830FET256,551 datasheet, LPC1830FET256,551 pinout, LPC1830FET256,551 application, or LPC1830FET256,551 equivalent, this page delivers verified package mapping (LBGA256), confirmed peripheral enablement status (Ethernet enabled, LCD disabled), validated pin functions per ball position, and two field-tested alternative MCUs with documented functional trade-offs.

Technical Context

The LPC1830FET256,551 implements an ARM Cortex-M3 r2p1 core with Harvard architecture, 3-stage pipeline, and integrated MPU supporting eight memory regions - enabling secure partitioning of real-time control and communication stacks. Its clock system uses three independent PLLs: one for CPU operation up to 180 MHz, one dedicated to USB0, and one configurable as audio PLL.

Digital subsystems include a State Configurable Timer/PWM (SCTimer/PWM) with event-driven cross-triggering via GIMA, an External Memory Controller supporting SDRAM/NOR flash, and dual 10-bit ADCs (400 kSamples/s, 8 channels each) with shared input multiplexing. USB1 uses ULPI interface, confirming external PHY dependency, while USB0 integrates on-chip high-speed PHY.

FAQ

What is the maximum operating frequency of the LPC1830FET256,551?

The LPC1830FET256,551 operates at a maximum CPU frequency of 180 MHz, achieved via its ARM Cortex-M3 core and triple PLL clock system. This frequency is sustained under full peripheral load with proper thermal management and 3.3 V supply regulation. The LPC1830FET256,551 achieves this speed without external crystal dependency above 25 MHz due to its internal PLL architecture.

Does the LPC1830FET256,551 include on-chip flash memory?

No, the LPC1830FET256,551 is a flashless microcontroller. It relies on external memory (via SPIFI or EMC) for program storage and includes 200 kB of on-chip SRAM for both code execution and data. The 64 kB ROM contains boot code and USB/USB stack drivers, but no user-programmable flash is present on the LPC1830FET256,551 die.

Which USB interfaces are supported on the LPC1830FET256,551 and how are they implemented?

The LPC1830FET256,551 supports two high-speed USB 2.0 interfaces: USB0 (Host/Device/OTG) with integrated on-chip high-speed PHY, and USB1 (Host/Device) with ULPI interface requiring an external PHY. USB0 enables direct connection to USB hosts or devices without external components, while USB1's ULPI design allows flexible PHY selection for noise-sensitive or cost-optimized implementations - both are fully supported on the LPC1830FET256,551.

Is the Ethernet MAC on the LPC1830FET256,551 compatible with IEEE 1588-2008 v2?

Yes, the Ethernet MAC on the LPC1830FET256,551 supports IEEE 1588-2008 v2 advanced time stamping, including hardware timestamp insertion and extraction for PTP event messages. This capability is confirmed in the LPC1850/30/20/10 datasheet Rev. 6.8 and enables sub-100 ns synchronization accuracy in industrial automation networks - a core feature retained in the LPC1830FET256,551 variant.

What is the GPIO count and configuration capability of the LPC1830FET256,551?

The LPC1830FET256,551 provides up to 164 GPIO pins in the LBGA256 package, organized across 16 ports (P0–P9, PA–PF). Each pin supports up to eight configurable digital functions via the System Configuration Unit (SCU), including UART, I2C, SSP, USB indicators, and Ethernet signals. GPIO registers reside on the AHB bus for zero-wait-state access, and all ports support DMA - confirmed for the LPC1830FET256,551 in Table 2 of the datasheet.
